Re: [Idr] New BGP capability to advertise running daemon version

Hello Donatas,

I do think that your suggestion is handy, but from security perspective it is risky if you are enabling such a feature in a non-trust environment. An implementation warning should be added for vendors/code developers not to enable this capability by default. Enabling such a functionality by default might result in your neighbors knowing your BGP implementation & its version, which might contain security risks.

In security section you refer to RFC3552. In section 6.1.1.4 (https://tools.ietf.org/html/rfc3552#section-6.1.1) of mentioned RFC same suggestion exists but only for SMTP.

Hi there!

I would like to propose a new idea of how to simplify the debugging process when dealing with lots of different BGP speakers and even more with different versions.

Basically, the implementation is very trivial, but it would be handy in cases when you should debug why some functionality does not work between two or more BGP speakers. Having this in place would speedup troubleshooting time. Even better if that comes to automation to gather information around all infrastructure you have.

The implementation and details are posted in this draft:
https://www.ietf.org/id/draft-abraitis-bgp-version-capability-00.txt

Waiting for comments.

Thank you!
